Abstract

The invention discloses a micro-vortex flocculation suspension rapid filtration device, and the device comprises a tank body, wherein an inner cavity of the tank body is divided into a flocculation area, a sedimentation area, a filtration area and a water storage area, and the bottoms of the sedimentation area and the filtration area are communicated to form a sludge discharge area. The cavity of the flocculation area is divided into a plurality of vertical shafts distributed in a grid shape through partition plates, the vertical shafts are vertically staggered and sequentially communicated, so that sewage entering the first vertical shaft flows in a vertical staggered mode in the serial connection direction of the vertical shafts, and the last vertical shaft is communicated with the upper end of the sedimentation area. The vortex flocculation assemblies are arranged in at least part of the vertical shafts and are used for generating tiny vortexes in the penetrating water body, so that the flocculation time is shortened, and the flocculation effect is improved. According to the device disclosed by the invention, the process combination of flocculation, precipitation and filtration is adopted, the high-efficiency flocculation area is arranged at the front end of the device, and a coagulant is added to react with particulate matters in sewage, so that the pollutant removal effect of the precipitation area is greatly improved, the effluent quality is greatly improved, and the operation cycle of the filtration area is prolonged.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a micro-vortex flocculation suspension quick filter device. Background technique [0002] The initial rainwater dissolved a large amount of acid gas in the air, vehicle exhaust, factory exhaust gas, etc., and after landing on the ground, it washed away pollutants on impermeable surfaces such as roofs and roads, making it contain a large amount of pollutants. Consolidated sewage includes rainwater, domestic sewage, and even industrial wastewater. It has the pollution characteristics of the three types of sewage, with many types of pollutants, high concentrations, and complex components. The direct discharge of initial rainwater or combined overflow sewage has caused serious damage to the water environment. At present, urban non-point source pollution has become the main cause of urban water pollution in my country. [0003] Suspended matter is an important carrier of pol...
